Before the change, the first control unit 110 configures operations of water supply, washing, rinsing, and dehydration according to the washing setting (C31) of the first washing unit 140 that is initially input, and the washing time is 31-hour (T31). Calculate

When the washing time is changed as the simultaneous termination is set (C32), the first control unit 110 adds a soaking stroke between the water supply and the washing stroke to change the total washing time from the 31st time (T31) to the 33rd time (T33). To).

In this case, the first control unit 110 may change the washing time by adding an anti-wrinkling stroke or a cooling stroke after the dehydration stroke. In addition, the first controller 110 may change the washing time by adding a waiting time between the washing stroke, the rinsing stroke, the dehydrating stroke, and the drying stroke, or delaying the start of any one stroke.

In addition, as shown in (b) of FIG. 7, the first control unit 110 sets the time of the drying administration in the initial washing setting (C33) consisting of water supply, washing, rinsing, dehydration, and drying at the same time. By increasing the washing setting (C34), the washing time is changed from the 36th time (T36) to the 37th time (T37).

In this case, the first controller 110 may increase the drying time by applying a control command to the first heater controller 170 to lower the set temperature of the first heater 171 or reduce the number of heaters that are operated. have. In addition, the first control unit 110 may change the washing time by increasing or decreasing the time for the washing stroke, the rinsing stroke, and the dehydrating stroke.

In addition, as the first washing unit and the second washing unit operate at the same time, the first control unit 110 does not simultaneously perform an operation according to water supply, dehydration, drying operation, and washing water heating in the first washing unit and the second washing unit. By delaying the operation of the first washing unit and the second washing unit to be terminated at the same time.

As shown in FIG. 8, when the washing setting of the first washing unit 140, that is, the first washing setting is input through the first input unit 144 (S310), the first control unit 110 may be configured to the first washing setting. Accordingly, the first washing time of the first washing unit 140 is calculated and displayed on the display unit through the first output unit 142 (S320).

The first control unit 110 transmits and receives data on the laundry setting through the

communication unit

180, 280 of the second control unit 210.

When the second laundry setting is input to the second laundry unit 150 (S330), the first control unit 110 determines that the first laundry unit and the second laundry unit operate simultaneously in response to the data received from the second laundry unit. In operation S350, the first washing time of the first washing unit and the second washing time of the second washing unit are compared.

The first controller 110 calculates a time difference between the end time of the first washing time and the second washing time, and compares the time difference with the set time (S360).

In addition, the first controller 110 compares the start time and the end time of the first washing unit, the start time and the end time of the second washing unit, respectively, and sets whether to end simultaneously. At this time, the start time is based on the time when the laundry setting is input.

When the time difference between the end time of the first washing time and the second washing time is less than or equal to the set time, the first control unit 110 sets the simultaneous termination so that the first washing unit and the second washing unit simultaneously end the operation (S370). As the setting time, the first setting time or the third setting time described above is applied.

On the other hand, when there is no separate input from the second laundry unit, or if the time difference between the end time exceeds the set time, the first laundry unit and the second laundry unit performs washing separately (S340).

At this time, the first controller 110 may set the simultaneous termination when the simultaneous termination key is input through the first input unit 144 even if the time difference between the end times exceeds the set time.

At the same time, the first control unit 110 changes the washing time according to the first washing time of the first washing machine and the second washing time of the second washing machine according to the setting so as to terminate simultaneously (S380).

The first control unit 110 transmits data on the simultaneous termination setting to the second laundry unit. In this case, when the first washing time is changed, the first control unit 110 transmits data on the simultaneous termination setting to the second washing unit, and when the second washing time is changed, setting the simultaneous ending and the second washing to the second washing unit. Send data about time changes.

When the first washing time is changed, the first controller 110 may increase or decrease the time for any one operation so that washing is terminated at a designated time according to the changed washing time, and add a waiting time between the operations. Alternatively, or by adding a soak stroke, anti-wrinkling stroke, cooling stroke, etc., the first washing unit and the second washing unit may be terminated at the same time.

In addition, when the second washing time is changed, the second control unit 210 may add the washing administration or change the time as described above in response to the data on the washing time change received so that the first washing machine and the second washing machine may be changed at the same time. Can be terminated.

The first control unit 110 outputs a notification according to the simultaneous end setting and information on the washing time to be changed through the first output unit 142 (S390).

In this case, the first control unit 110 may display the information on the simultaneous termination notification and the change in the washing time through the display unit, and in some cases, display a guide message on whether to proceed with the change in the washing time.

After displaying a guide message on whether to proceed or not, if a progress key is input through the first input unit 144 correspondingly, the operation proceeds according to the washing time changed by simultaneous termination setting, and when a release key is inputted. The simultaneous shutdown setting is released and the first laundry unit and the second laundry unit perform separate washing according to the respective washing settings.

When the simultaneous termination is set, the first laundry unit and the second laundry unit simultaneously wash in response to the changed washing time, and are terminated at the same time (S370).

When the laundry is finished, a notification of the end is output to allow the user to collect the laundry.

As shown in FIG. 9, when the washing setting of the first washing unit 140, that is, the first washing setting is input through the first input unit 144 (S410), the first control unit 110 may be configured to the first washing setting. Accordingly, the first washing time of the first washing unit 140 is calculated and displayed on the display unit through the first output unit 142 (S420).

The first control unit 110 controls the washing to be performed by applying a control command to the first motor driving unit 130 and the first heater control unit 170 according to the first washing setting input.

Accordingly, the first washing unit 140 operates to perform washing (S430). In this case, washing includes all operations including washing, rinsing, dehydration, and drying.

When the second washing unit 150 is input to the second washing unit 150 while the first washing unit 140 performs an operation according to the first washing setting (S440), the first control unit 110 washes the first washing unit. The setting time is input or the elapsed time after the first washing unit starts washing (S460). In this case, the second setting time described above is applied to the setting time.

communication unit

180, 280 of the second control unit 210.

When the second washing unit 150 is not input to the second washing unit 150 while the first washing unit 140 performs the operation according to the first washing setting, the first washing unit 140 does not correspond to the simultaneous washing condition. Perform.

In addition, even when the washing setting is input by the second washing unit while the first washing unit performs an operation, when the setting time has elapsed after the first washing unit operation, the first control unit 110 does not set the simultaneous washing, and the first washing unit And second washing unit to perform the washing individually according to each washing setting (S450).

On the other hand, when the laundry setting is input by the second washing unit while the first washing unit is performing the operation, the first control unit 110 starts the washing setting of the second washing unit after the first washing unit starts the operation. If the elapsed time is less than or equal to the set time, the simultaneous end is set such that the first laundry unit and the second laundry unit are terminated simultaneously (S470).

The first controller 110 compares the first washing time with the second washing time to change at least one washing time (S480).

When the first washing time is changed, the first controller 110 may change the washing time by adding a predetermined operation or by changing a preset operation time. When the second washing time is changed, the first control unit 110 transmits data on the simultaneous termination setting and the washing time change to the second washing unit 150. Accordingly, the second control unit 210 changes the second washing time by adding an operation or changing an operation time.

When the washing time is changed, the first control unit 110 and the second control unit 110 may operate at the same time as the first washing unit and the second washing unit simultaneously operate, so that water supply, dehydration, drying, and washing water may cause vibration or increased power consumption. The washing time may be changed so that an operation such as heating is not performed at the same time.

The first control unit 110 outputs a notification according to the simultaneous end setting and information on the washing time to be changed through the first output unit 142.

The first laundry unit and the second laundry unit simultaneously perform washing in response to the changed washing time, and are terminated at the same time (S490).

When the laundry is finished, a notification of the end is output to allow the user to collect the laundry. At this time, as the operations of the first laundry unit and the second laundry unit are terminated at the same time, the user can recover the laundry of the first laundry unit and the second laundry unit at once.

Therefore, according to the present invention, when the first laundry unit and the second laundry unit operate at the same time for the first laundry unit and the second laundry unit that perform washing independently, the first laundry unit and the second laundry unit are set to end the operation simultaneously. The laundry of the laundry part and the laundry of the second washing part can be recovered at once, so that the laundry can be easily recovered.
